Title: Decontamination of cork wastewaters by solar-photo-Fenton process using bleaching wastewater as H2O2 source
Issue Date: 2011
Abstract: This paper reports on a treatment strategy of cork wastewaters through the design of a solar-photo-Fenton process using cork bleachingwastewater as hydrogen peroxide (H2O2) source, as a pre-oxidation step, before a conventional biological oxidation process. Thismethod proved to be efficient, achieving mineralization rates higher than 90% for different iron concentrations (2080 mg Fe L1).Higher iron concentrations resulted in the lower energy consumption and 60 mg Fe L1 was selected as the optimum dose for 91% mineralizationand used for biodegradability studies. According to the ZahnWellens test, the optimum phototreatment energy to achieve abiodegradable effluent is 13.6 kJUV L1 (65% mineralization), which corresponds to H2O2 consumption of 76.1 mM (approximately 8.5 Lof cork bleaching wastewater (at 7.7 g H2O2 L1) for 15 L of cork boiling wastewater).
